title: Chemical probes for water oxidation cycle of photosystem II: Part 2--Effect of histidine modifying reagent on thermoluminescence peaks of spinach chloroplasts.
abstract: A modification of water oxidation complex in spinach chloroplasts by rose bengal (RB), a known histidine modifying agent, has been studied using thermoluminescence (TL) technique. The changes in the TL profiles at low concentrations of the dye are explained on the basis of alterations in the protein dynamics while those at higher concentrations of the dye are related to the oxidation of histidine residues.
